Thanks GMayor and Moonshine

I found a simpler and faster way, that uses a macro that GMayor helped me in the past. (thanks for that GMayor).

I save the Word document as pdf in the same folder using the macro and then I open the pdf with pdf exchange viewer (which is free I guess for personal and commercial use, or at least this is what I understand from their website)

With PDF exchange viewer I export the pdf as pictures and It gives automatically the name of each picture (Deviz P1 for the first page, Deviz P2 for he second page, etc).
